摘要:
传统的物联网通信技术 3G、WI-FI 等,虽能满足一般的通信需求,但其功耗高,成本高等劣势成为限制物联网技术发展的因素。 与此同时,NB-IoT 技术的优势逐渐显现,可以满足物联网的不同需求,成为相关开发人员进行产品研发的首要选择。 NB-IoT 全称为基于蜂窝的窄带物联网,是近几年新兴的一种物联网通信技术,同时也成为了万物互联网的一个重要分支。 该技术相比于 4G 技术、WI-FI 技术、GPRS 技术等,具有低功耗、低成本、广覆盖、海量连接等技术特点,并可直接部署于 GSM 网络,UMTS 网络或 LTE 网络。 为了更全面地了解 NB-IoT 技术,对 NB-IoT 技术的基本架构以及关键技术进行阐述,并结合其他物联网通信技术进行对比分析,重点剖析其在农业应用以及智能交通领域的典型案例,并探讨了该技术在未来发展过程中所面临的挑战。
Abstract:
Traditional communication technologies of the Internet of Things, such as 3G and WI-FI, can meet the general communication needs,but their disadvantages, such as high power consumption and high cost,have become the factors limiting the development of the Internet of Things. At the same time,the advantages of NB-IoT technology are emerging gradually,which can meet different needs of the Internet of Things and become the first choice for relevant developers to carry out product research. NB-IoT,known as the narrow-band Internet of Things based on cellular network,is an emerging communication technology of the Internet of Things in recent years,and has also become an important branch of the Internet of everything. Compared with 4G, WI-FI, GPRS, etc, it has some technical characteristics of low power consu-mption, low cost, wide coverage and massive connection, and can be directly deployed on GSM network,UMTS network or LTE network. In order to understand NB-IoT technology more comprehensively,the basic architecture and key technologies of NB-IoT technology are expo-unded. Combined with the comparative analysis of other Internet of Things communication technologies, typical cases of NB - IoT in agricultural applications and intelligent transportation are analyzed, and the challenges faced by the technology in the future development are discussed.
